Taker/Lesnar should be good. Taker's managed to be a prettu hard worker these days, and Lesnar will likely feel he needs to bust his ass to try to show up Angle in Angle's match with Taker the other week.
No Mercy is going to be a bitchin' PPV. That, Angle/Cena, Los Guerreros vs. one another, WGTT on the card in some capacity, and throw in a good Cruiserweight match, and we're cookin'. I dunno if Benoit will finish the angle with Rhyno by then, but hopefully they'll be on the PPV, if not against each other then against some decent opponents.
